IRA HUTCHERSON, OF KEOKUK, IOWA.

Application led March 20, 1922. SerialiNo. 545,111.

T all whom it may concern.'

Be it known that l, IRA l'lUTcI-innsoiv, a citizen of the United States,and a resident of leokuk, in the county of Lee and State of lowa, haveinvented a certain new and useful Combination Woven-W'ire Stretcher andHoist, of which the following is a specification.

rIhe object of my invention is to provide a combination woven wirestretcher and hoist, the parts being of simple, durable andcomparatively inexpensive construction.

More particularly my invention relates to a structure especially adaptedto the stretching ot wire `fences or the like, the parts being` soarranged'that they may be easily assembled or disassembled, and can beoperated in a minimum amount of time and eiliort.

Still another object is to provide such a structure wherein the partsmay beused as a hoist or may be used as a fence stretcherinterchangeably.

With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various parts of mydevice, whereby the obliects contemplatcd are attained, as hereinaftermore Jfully set i'orth, `pointed out in my claim, and illustrated in theaccompanying drawings, in which:

Figure 1 is a side elevation of my invention showing it used as a Jfencestretcher.

Figure 2 shows my invention being used as a hoist.

Figure 3 is a central, sectional view taken on line 9)#3 of Figure 1.

Figure t is a perspective View of one oi. the brackets, forming a partof my invention; andv Figure is a central sectional view taken throughone of the combined worm wheels and cable drums.

ln the accompanying drawings, I have used the reference numeral 10 toindicate generally a supporting rod which is provided with a bracket Aat its upper end and a bracket B at its lower end.

The brackets A and B are each similar in construction and are clearlyillustrated in Figure 4 of the drawings.

The brackets A and B are each provided with an opening 11 designed toreceive the supporting rod 10. i

A small opening 12 is provided in the brackets A and B so that a pin 13may .extend therethrough. The pin 13 also extends through the supportingrod 1()A and thus sesurely holds the brackets in proper position on thesupporting rod' 10. y

A clevis 14 is fixed to each of the pins 13, and a iiexible element 15is secured to each of the clevises 14. The tree ends of the flexibleelements or chains 15 are provided with hooks 16 which are designed tobe receivedin any| of the links in the chain 15.

The flexible elements or chains 15 may be extended around a fixed post17, as clearly shown in Figure 1 of the drawings.

The brackets A and B are each provided with an opening 18 for forming aAbearing member for the rod 19. The rod 19 is provided with a pair otspaced worms 20.

The forward ends of the brackets A and B are bifurcated so as to formthe fingers 21. The ends ofthe lingers 21. are provided with a pair ofregistering openings 22, through which may be extended the bolt or thelike 23.

Rotatably mounted on the bolt 23 and between the lingers 21 of thebrackets A and B is a combined worm wheel and cable drum 211. Each ofthe combined worm wheels and cable drums are designed to mesh with theworms on the rod 19.

The combined worm wheels and cable drums are formed of two similarhalves, as clearly shown in Figure 5 of the drawings.

Secured to each of the cable drum portions 25 are the cables 26. Thecables 26 have their forward ends xed to a clevis 27. Each of theclevises 27 may be secured to a bar 28. The bar 28, in turn, is securedto a woven wire fence 29 by means ot the bolts 30.

In order to rotate the worm wheels by operation of the rod 19, l employa crank 31.

From the construction of the parts just described, it will be seen thatrotation of the rod 19 in one direction, will cause the woven wire fenceto be drawn `tightly so that it may be stapled to the ordinary tencepost.

The Worm and Worm Wheel construction form a brake against movement,which might cause the Woven Wire fence to be released.

The rod 19, however, may be rotated in either direction for eitherreleasing or Winding the 'cable 26 on 'the drums. Movement, however, ofthe drums for imparting rotation to the rod 19 Will not be had, due tothe Worm and Worm Wheel construction.

In Figure 2 of the drawings, I have shown my invention as being used:tor hoisting purposes. In this form of use of my invention the flexibleelements are secured 'to' a beam In place of the crank 31 on the rod 19,I employ a chain gear pulley 33 which is operated by the chain 34C.

'4 From the construction of the parts just described,rit Will be seenthat movement ot thefchain will cause the chain gear pulley 33 to berotated for operating the rod 19.

` f ItY vvill be seen that my invention is very! 'simple and that theparts may be easily assembled or disassembled and can be usedinterchangeably for various purposes.

Some changes may be made in the construction and arrangement ot thevarious parts of my invention, Without departing from the real spiritand purpose of my invention and it is my intention to cover by my claim,any modied forms of structure or use of mechanical equivalents, whichmay be reasonably included Within their scope.

I claini as my invention:

In a device of the class described, a pair of brackets, each having apair of openings, a supporting rod received in one of the openings ofeach bracket, pins extended through the brackets and through the rod forfixing the brackets thereon and supporting them in spaced relation, saidbrackets having` a pair of spacedL ears thereon, a second rod journalledin the other openings in said brackets, a crank on said second rod, acom bined worm Wheel and cable drum ournalled between said ears on eachof said brackets,

Worms spaced from each other iixed to said second rod and arranged tomesh with the combined worin xpvheels and cable drums, said combinedWorm Wheels and ci ble drums including a pair ot similar members havingtubular cable receiving portions and flanges provided With teeth ontheir adjacent faces for forming the Worm Wheels.
